solar panel
Definition
Solar panels are devices that convert sunlight into electricity. They are made up of solar cells, which are made of semiconductor materials like silicon. When sunlight hits a solar cell, it creates an electric current.
Solar panels can be used to power homes, businesses, and other buildings. They can also be used to charge batteries for solar-powered devices, such as laptops and cell phones.
Solar panels are a clean and renewable energy source. They do not produce greenhouse gases, and they are not limited by the availability of fossil fuels. Solar panels are becoming increasingly popular as a way to reduce our reliance on fossil fuels and combat climate change.
